Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a glass or plastic globe to a lighting equipment body.

[Background Art] When wearing a glove on an instrument body, a common method is to provide a threaded portion on the outer periphery of the glove and the inner periphery of the instrument body, and screw the two together to fix the two. Since it is necessary to mold the screw into the main body, there is a problem in that a mold and the like are required, which increases the cost.

FIG. 3 shows a simple glove attachment structure in which the constriction 2 formed at the opening periphery of the glove 1 is attached to the instrument body at three locations around the circumference.
The device is locked by two locking protrusions 4 protruding from the inner surface of the device and a thumbscrew 6 screwed into the vertical portion 5 of the device body 3. 7 in the figure is a socket stand,
8 is a socket, 9 is a lamp, and the appliance body 3 is fixed to a ceiling surface 10 or the like.

However, in this conventional structure, the thumbscrew 6
If the screws are screwed in too much, there is a risk that the glove 1 will be damaged due to stress concentration, and if the screws are not screwed in too much, the screws may loosen due to vibrations, etc., and the glove 1 could fall. For this purpose, as shown in Figure 1,
A spring plate piece 11 is placed between the globe 2 and the thumbscrew 6.
It has been proposed that the This spring plate piece 11 has a bent part 11a at the upper end and a convex curved part 1 at the lower end.
1b is formed, and the bent part 11a is fixed to the lower surface of the instrument body 3 by a rivet 12, and the instrument body 3 is fixed to the lower surface of the instrument body 3.
The tip of the thumbscrew 6 screwed into the vertical part 5 of
The convex curved portion 1 is pressed against the back surface of the convex curved portion 11b, and the convex curved portion 1 is engaged with the constriction portion 2 of the glove 1.
The thumbscrew 6 prevents the thumbscrew 1b from bending, and at the same time prevents the thumbscrew 6 from loosening by pressing the thumbscrew 6 with the convex curved portion 11b.

In this case, the problems of the conventional example are reduced, but
As the thumbscrew is screwed in, there is a risk that the thumbscrew will directly press the glove through the convex curved part and damage the glove.To avoid this, reduce the threading allowance of the thumbscrew. There is a risk that the thumbscrew will not be able to press the spring plate piece sufficiently, making the glove holding unstable.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to eliminate the risk of the glove breaking due to the pressure of the thumbscrew or the glove falling due to the thumbscrew loosening. To provide a structure for attaching a glove to an instrument body, which allows the glove to be held securely without the need for a glove.

[Disclosure of the invention] The present invention provides a glove attachment structure in which a constriction formed at the periphery of the opening of the glove is locked at three points on the outer periphery, and one of the above-mentioned locking portions is connected to the instrument body at the upper end. A spring that is fixed and has convex curved parts on both sides of the lower end that engage with the constriction of the glove, and has a receiving piece at the center of the lower end that abuts the tip of a thumbscrew that is threaded onto the vertical piece of the instrument body. It is characterized by being formed from a piece of plate.

[Example] In the present invention, a second spring plate piece 11 is used as the spring plate piece 11 that locks on the constricted portion 2 of the opening periphery of the glove 1 together with the two locking protrusions 4 protruding from the inner surface of the instrument body 3. Use what is shown in the diagram. That is, the receiving piece 1 has convex curved parts 11b formed on both sides of the lower end of the spring plate piece 11, and the thumbscrew 6 comes into contact with the center of the receiving piece 1.
1c, and a recess 13 is provided at a portion of the receiving piece 11c where the thumbscrew 6 comes into contact. With this configuration, glove 1
Since the globe 1 of the spring plate piece 11 contacts the spring plate piece 11 at two places, the holding becomes more reliable, and the globe 1 of the spring plate piece 11
By providing a distance between the part that contacts the thumbscrew 6 and the part that contacts the thumbscrew 6, it is possible to increase the springiness and provide a margin for screwing the thumbscrew 6.

[Effects of the invention] As described above, the present invention has a structure in which the glove is locked at three points on the outer periphery. Since the glove is equipped with a spring plate piece that has a convex curved part that locks into the part, and a receiving piece at the center of the lower end that comes into contact with the tip of a thumbscrew screwed into the vertical piece of the instrument body, If the spring plate is circular, the two convex curved portions of the spring plate come into contact with the glove, which not only makes glove holding more reliable, but also increases the springiness of the spring plate, and at the same time makes it easier to grip the glove. This allows extra allowance for screwing in the screws, which not only prevents the glove from falling off due to loosening of the thumbscrew, but also prevents the glove from falling due to excessive stress being applied to the glove when it is worn. It is possible to more reliably prevent damage and at the same time, securely hold the glove.
